Deuteronomy 18:20-22

Revised Geneva Translation

²⁰ ‘But the prophet who shall presume to speak a word in My Name whom I have not Commanded to speak, or who speaks in the name of other gods, that same prophet shall die.’

²¹ “And if you think in your heart, ‘How shall we know the word which the LORD has not spoken?’

²² “When a prophet speaks in the Name of the LORD, if the thing does not follow or happen, that is the thing which the LORD has not spoken. The prophet has spoken it presumptuously. You shall not be afraid of him.”
